Lastcloud is an api mashup/hack that finds cloudcasts (mixes, radioshows, podcasts etc) on Mixcloud.com that feature music from your favorite artists on Last.fm. Lastcloud is a Django app, written in Python. The frontend uses jQuery and Masonry.
Installation / Use
I've not yet made a packaged version of this app. But you can download the source from Github and try it out. There are no requirements beyond the Python Standard Library, but you'll need an api key from Last.fm which you should paste in your settings.py or similar.
Demo / Example
